FP green turbo worth the price?
The stock Evo cast manifold, when properly ported is not that bad actually. In fact, the Full Race manifold is only good for a couple more ponies than the stock ported piece. The difference is miniscule and not worth the $ performancewise.
I beg to differ. If you talk to Geoff @ Full-Race, which I do on a monthly basis (I am running his products on my S2000 and would run them on my wife's Evo if I went aftermarket), his turbo manifold will make between 10-60awhp depending on the turbo (from OEM to GT35R) with all other variables remaining the same.

I would attribute a portion of your gains to the aftermarket turbo manifold and not soley the different turbo. The OEM turbo manifold is a log-style manifold, and is designed more for longevity than overall performance. A tubular style manifold, such as the Full-Race manifold, will put any log-style manifold to shame with all other variables remaining the same.
What style manifold does the ATP use?

zeller - i'm sorry but if you hit 475 as you think you would've hit on race gas with an ATP 3071 kit, then that'd be a world record.

you've gone off-topic compared to the point which you were originally trying to make - that tubular manifolds are better than the stock manifold for the stock turbo...as zeller quotes you above.
Buschur did extensive testing of many tubular manifolds vs his ported/coated stock manifold and it was found that the full race manifold was the only one that had slight gains over the ported/coated stocker....thus your 10-60whp estimate is a bit skewed since we're talking about stock turbo (or green which is stock-turbo bolt-on style) applications, not other types of turbos.

Why the 35r anyway when i heard the 3076r is better to use up to 30psi and at 30 psi with full bolt ons and aem ems you would definitely be putting down some horse and torque obviously

For starters if you would read what I wrote all I said is that that is what AMS said because of how my car was responding on the dyno, not what I said!!!! I guess we will just have to wait and see in the spring when I do a race tune!! With the bolt ons that I have right now it would be hard reach but 475whp is not out of the question for a 3071 kit. With race gas and more bolt-ons 75whp would not be to hard to gain!
for the money you can't beat the FP Green! 400 WHP @22 psi on 93 oct is pretty darn good and I only paid $1500 shipped w/the $300 core charge. I'll bet that once I get the ignition issue taken care of we can break 400 WHP up another 10 whp on pump. I'll wager too that we can get to 455-480 whp w/ a race fuel tune @ 28psi, but there's only one way to know and that's to do it! I should be able to do it in about 3 weeks to a month.
It's hard to actually use this term with all the Environazis saying it all the time, but: GO GREEN!!

This topic has been well expounded and if there is any proof other than verbal, that going from a BR or PPI ported stock manifold to a Full Race tubular header(or any other header for that matter), on a Green equipped car will gain more than 4 WHP then post the graph.
Personally, IMO a tube header for a stock type turbo is a low returns investment. Eventually, I'll just port my own stock manifold as that's all I can afford to do right now. I'd rather spend my $900 on a Aquamist kit. But hey, that's consumer choice.
There is no arguement here that the green is a monster of a turbo for what it is. All I am saying is that I have the ATP GT3071R .63ar kit on my car and am putting down 401whp, 21.5 psi, reflash, and don't have all the bolt-ons you can get yet and AMS said that my car reached full boost at about 4,300rpm and pulls all the way to the end on a conservative tune. If I were to switch turbo's to the green on the same day I would have made less power, that is all I am saying. The green is great but for the money don't count out the atp stuff either. I know this is all here say but AMS said that if I did meth or race fuel that I would have no trouble seeing 475+whp and I don't think you would see that on a green with my mods!! Anyway after I get to the track I guess I will see. I am not one to boost up something without hard data so until I get to the track I am just saying the car feels great!
You are not going to make 475awhp on meth or race fuel on an ATP 3071. The end.
Given a stock or stocklike upgrade turbo, with all else remaining constant, the measurable gains in swapping from a well ported stock manifold, such as a BR or PPI, to a tubular header is minimal, and in my opinion not worth the additional cost.

As I mentioned earlier, I sent Geoff a message asking for him to provide more info on his manifold, and hopefully that would include dyno graphs.
